Chemical Structure

2'-Benzyl-1'-oxo-1',4'-dihydro-2'h-spiro[cyclohexane-1,3'-isoquinoline]-4'-carboxylic acid CAS 1283481-92-4 chemical structure

Description

2'-Benzyl-1'-oxo-1',4'-dihydro-2'h-spiro[cyclohexane-1,3'-isoquinoline]-4'-carboxylic acid (CAS 1283481-92-4) is a high-purity analytical reference standard with the molecular formula C22H23NO3 and a molecular weight of 349.42 g/mol.

2'-Benzyl-1'-oxo-1',4'-dihydro-2'h-spiro[cyclohexane-1,3'-isoquinoline]-4'-carboxylic acid (C22H23NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2'-Benzyl-1'-oxo-1',4'-dihydro-2'h-spiro[cyclohexane-1,3'-isoquinoline]-4'-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
